Embodiment Construction

[0017] Below in conjunction with accompanying drawing and embodiment, the present invention is further described:

[0018] As shown in Figure 1, the uniform heating system for liquid biochemical reaction of the present invention includes a heating tube 1, a platinum resistor 2, a support 7, and a control circuit.

[0019] The heating tube 1 is wound on the support 7, wound in two layers, and the platinum resistance 2 is placed in the middle to measure its temperature. The upper end of the support 7 has the liquid inlet 8 and the liquid outlet 9 of the heating tube 1, and the liquid inlet 8 and the liquid outlet. 9 is connected to the peristaltic pump 10, and the two liquids are mixed uniformly and slowly inflow from the liquid inlet 8 of the heating tube and flow out from the liquid outlet 9 under the action of the peristaltic pump 10.

[0020] The control circuit is composed of a temperature control instrument 3, a power adjustment module 4, a regulated power supply 5 and a w...

Abstract

The invention relates to a uniform heating system used for liquid biochemical reaction, comprising a heating pipe, a platinum resistance, brackets, and a control circuit. The invention has the characteristics that the heating pipe and the brackets are enwound for twice; the platinum resistance which is used to measure temperature is arranged between the brackets. The top ends of the brackets are provided with a liquid intake and a liquid outlet of the heating pipe. The liquid intake and the liquid outlet are connected with a peristaltic pump. Under the action of the peristaltic pump, the two liquids are mixed uniformly, flow into the heating pipe from the liquid intake slowly, and flow out of the heating pipe from the liquid outlet slowly. The uniform heating system has the advantages of simple structure, convenient operation, high efficiency, safety and uniform heating.

Description

technical field [0001] The invention relates to a liquid heating system, in particular to a liquid heating system which is mainly used for uniform heating of two liquids. Background technique [0002] Two different liquids have the most sensitive biochemical reactions at a specific temperature. In order to achieve this specific temperature, the following two methods are mainly used. Biochemical reaction, in this way, the gas heat transfer coefficient is relatively small, the heating time is relatively long, and it is difficult to achieve uniform heating; the second is to place it in a constant temperature water bath for heating. This method has large equipment volume, uneven heating temperature, and large heating power. The energy consumption is large and the structure is complex. In order to ensure the constant water temperature and enhance the heat exchange effect, it needs to be stirred. The currently disclosed flowing liquid heater (Patent No. ZL200520109719.5) is heate...
